What are good women’s polarized sunglasses?
In the previous article, we discussed “How do polarized glasses work?”. In this article, let’s talk about “What are good women’s polarized sunglasses?”.
What is a polarizer?
The polarizer is manufactured according to the principle of polarization of light. We know that when the sun shines on the road or water, it directly irritates the eyes, making the eyes dazzling, fatigued, and unable to see things for a long time. Especially when you are driving a car or engaging in outdoor activities, it not only affects your work and entertainment mood, but even affects your judgment of objects and causes danger. Long-term exposure to direct sunlight will also cause rapid vision loss and form myopia, hyperopia, astigmatism or cataract.
How to distinguish the polarizer?
When buying a polarizer at a regular glasses shop, there will be a test film with some pictures inside. You can’t see it without the polarizer. You can see it as soon as you put it on. In fact, this test film is specially made. Using the principle of polarization, the polarizer can see the parallel light emitted by the picture inside, so that you can see the picture hidden inside. It is not a perspective, so it can be used to detect whether it is a real polarizer.(https://www.koalaeye.com/blogs/our-stories)
When you buy the polarizer, stack two polarized lenses vertically, and the lenses will appear opaque. The reason is that the special design of the polarizer lens only allows parallel light to pass through the lens. And most of the light is blocked when the two lenses are stacked vertically. If there is a phenomenon of opacity, it proves to be a polarizer.
Place the lens and the LCD screen in parallel and overlap. Turn the polarizer. Looking at the LCD screen through the polarizer, you will find that the LCD screen will brighten and darken as the polarizer rotates. The different colors of the LCD screen are exactly the polarization principle of the liquid crystal molecules used. If there is no change no matter how it turns, it is not a polarizer.
Popular brands of polarized sunglasses
Ray-Ban was founded in the United States in 1930, as a symbol of American culture nowadays. Ray-Ban polarized sunglasses are with reinforced polarized glass. The optical performance is stable and the service life is long. Under the same temperature environment, the lens has a small probability of deformation and is not easy to scratch. The visual effect is excellent, and it has a good eye protection function.
Oakley is a famous sports outdoor brand in the United States. As early as the 1990s, Oakley sunglasses were one of the most popular trends. Oakley's polarized sunglasses are mainly used in cycling, skiing and daily life. The lenses generally use the exclusive Oakley Prizm? technology. Prizm technology enhances the visual field imaging effect without reducing the color of conventional lenses, which is equivalent to a sharpening effect.
